Answer:

y = -2

Step-by-step explanation:

The line that is perpendicular to y-axis will be a horizontal line so it's slope is 0 => y = 0x + b or y = b

Using (5,-2) => -2 = b => b = -2

then y = -2

II. Let f(x) = 9 – x , g(x) = x2 + x, and h(x) = x – 2. Compute the following:
Neko [114]

Answer:

h(g(x))=x^2+x-2

h(g(f(x))= x^2-19x+88

Step-by-step explanation:

<u>Composite Function</u>

Suppose f(x) and g(x) are real functions, the composite function named (f\circ g)(x) is defined as:

(f\circ g)(x)=f(g(x))

The composite function can be found by substituting g into f.

We are given these functions:

f(x)=9-x

g(x)=x^2+x

h(x)=x-2

Find:

a) h(g(x))

Substituting g into h:

h(g(x))=x^2+x-2

b) h(g(f(x))

First we find g(f(x)):

g(f(x))=(9-x)^2+(9-x)

Operating:

g(f(x))=81-18x+x^2+9-x

Simplifying:

g(f(x))=90-19x+x^2

Now find h(g(f(x)) replacing the above equation into h:

h(g(f(x))= 90-19x+x^2-2

Simplifying and rearranging:

h(g(f(x))= 88-19x+x^2

h(g(f(x))= x^2-19x+88

Solve the following equation. 7(x - 2) = 3(x + 4)
scoray [572]

Answer:

x = 6.5

Step-by-step explanation:

You have to apply the distributive property of multiplication:

7(x-2) = 3(x+4)

7x - 14 = 3x + 12

7x - 3x = 12 + 14

4x = 26

x = 6.5
